OPHTHALMIC MOUNTIN Application led February 25, 1924. Serial No.694,984.

To all 'whom t may concern:

Be it known that I, ALBERT A. JEANERET, a citizen of the United States,and a resident of lVatertown, in the county of Middlesex and State ofMassachusetts, have invented a new and useful Improvement in OphthalmicMountings, of which the` following is a specification.

The present invention relates to ophthalmic mountings, and moreparticularly to spectacles of the all-shell type.

Spectacles of the above-described character comprise lens-holding rims,a bridge and temple end pieces, all integrally connected together andconstituted of some non-metallic material, such as zylonite,

. horn, tortoise shell and the like. The spectacles are provided withtemples constituted of like material that are hinged to the end pieces.The temples are provided with earengaging or skull-engaging hooks. lVhenthe temples are folded, these hooks project to one side of the rims. Afolded pair of spectacles of the all-shell type is therefore ulky, andrequires a large spectacle case. As the non-metallic material is noteasily fiexible, any attempt to force the hooks to overlie the rims willresult in weakening the hinge connection between the temples and the endpieces so that the bulky cases have been conceded to be a necessaryevil.

An object of the present invention is to provide an ophthalmic mountingofthe above-described character that shall be foldable into more compactshape, making it possible to use a smaller spectacle case; and with thisand other objects in view, the

nature of which will appear from the following' description, taken inconnection wlth the accompanying drawings, the invention consists of theimproved opthalmic mounting hereinafter described, illustrated in thedrawings, and defined in the appended claims.

In the drawings, Fig. 1 is a rear elevation of a pair of spectaclesconstructed according to a preferred embodiment of the presentinvention, the temples being shown folded; Fig. 2 is a similar view withthe temples unfolded, or open; Fig. 3 is a view similar to Fig. 2 of amodification; and Fig. 4 is a view upon a reduced scale, showing thetemples in position in a spectacle case.

' Ihe illustrated `ophthalmic mounting comprises two lens-holding rims 2and 4 integrally connected together by a bridge 6, and all constitutedof non-metallic material. The surface 8 of the bridge is adapted to seatupon a wearer-s nose. The rims are each provided with an integral endpiece 10 at a point approximately diametrically opposite to the bridge6. One of the hinge plates 12 of a two-plate hinge is secured to one ofthe end pieces 10, and one of the hinge plates 14 of another two-platehinge is secured to the other end piece 10. -The two plates 12 vand 16,and 14 and 18, re-

spectively, of each hinge are pivoted to- .of temples 2O and 22, thattherefore pivot about the pivot pins.

Ophthalmic mountings as thus far described are old and well known, butthe temples of the old mountings are adapted to pivot about their hingessubstantially in a plane passing through the end pieces 10 andperpendicular to the plane of the rims 2 and 4. The rearwardly disposed,curved ear hooks 24 of the temples,.when folded, therefore project downbelow the rims 2 and 4. It is impossible to place folded spectacles ofthis character into a spectacle case 26 unless the case is made wideenough to include notonly the rims and the bridge, but the projectingtemples, as well. A case of such large size is very inconvenient tocarry around, with the result that the s ectacles are placed directly inthe poc et, without a case, and this causes large breakage.

According to the specific embodiment of the present invention that isherein illus' trated and described, the' hinge plate 12 is secured toits end piece 10 in such fashion that its. pivot ears 17 are obliquelydisposed to the line 28 joining the end pieces 10 and passingsubstantially through the centers of of the rims. The other hinge plate16 of the hinge pivots about its pivot pin 15 in Y line 30. The hingeplate 14. is similarly secured to the other hinge plate in suchv passingthrough the dotted vline 32. The

intersecting line of the oblique planes passing through the lines 30 and32 is indicated by the point 34, which is situated farther from thenose-seating portion 8 of the bridge 6 than other portions of thebridge, and the pivot pins 15 converge'toward a point on the other sideof the nose-bearing portion v8. The ear hooks of the temples willtherefore overlie the rims when the temples are folded, as isillustrated in. Fig. l. A folded pair of spectacles of this constructonwill therefore readily7 be received in a spectacle case 26 of moderatedimensions, as is illustrated in Fig. 4.

.As the hinge plates are elongated, being provided with substantiallyparallel walls 36, substantially parallel to the pivot ears, andsubstantially parallel, respectively, to the lines 30 and. 32, the wallsare necessarily disposed at an angle to the end pieces 10 shown in Figs.1 and 2. According to the modifications shown in Fig. 3,' however, theend pieces 10 project from the rims in directions substantially parallelto the lines 30 and 32, respectively. This gives a more finishedappearance to the spectacles when the temples are unfoldedoropen, as isillus-v trated in Fig. 3.

It will, of course, be understood that the invention is notrestricted tothe exact embodiments thereof that are illustrated and described herein,as changes may be readily made by personsskilled in the art without inthe least departing from the spirit 'and scope of the invention, asdeiined in the appended claims.
